Description

Technical Field

[0001] The utility model belongs to the technical field of wine-making sampling, and more specifically relates to a wine-making fermentation tank sampling device. Background Art

[0002] Among the raw materials for brewing, most of them are grains such as sorghum, rice, and beans. Brewing is done by bacterial fermentation. During the brewing process, the fermentation of wine is a complex chemical reaction process. Experienced staff are required to pre-estimate the fermentation time according to different environments and room temperatures. After reaching the expected time, the wine inside the fermentation tank is usually extracted by staff for inspection and tasting to determine whether the wine meets the standards.

[0003] At present, the existing method for sampling brewing wine is generally to directly open the fermentation tank lid, and then manually hold the sampling device to sample the wine in the fermentation tank and store it in an uncovered sampling cup for staff to taste. During the sampling process, this sampling method causes air or dust to enter the fermentation tank or the sampling cup because the fermentation tank and the sampling cup are always connected to the outside space, which not only affects the fermentation quality of the finished wine, but also may cause dusty wine to be extracted and need to be re-sampled, resulting in poor sampling effect and low sampling efficiency. In addition, during the fermentation process, the upper and lower layers of the wine are in two completely different states. The above sampling method requires the staff to reach the fermentation tank and hold the sampling device all the time, and can only sample the upper or lower layer of the wine at a time, which is time-consuming and labor-intensive, and has the problems of low sampling efficiency and high labor intensity.

[0023] In order to explain the technical content, purpose and effect of the present invention in detail, the following is a description of the embodiments and the accompanying drawings. It should be noted that the words "upper" and "lower" used in the following description refer to the attached Figure 2 and Figure 3 In the directions, the words "bottom" and "top" refer to the Figure 2 and Figure 3 The direction towards the geometric center of a specific component.

[0024] The key concept of the present invention is that: the conveying mechanism plays the role of automatically conveying the sampling bottle 7 to the bottom of the liquid outlet pipe 1; through the liquid outlet pipe 1, the annular portion 4, the sealing cover 2, the groove, the liquid outlet channel 3 and the compression spring 6, under the elastic force of the compression spring 6, the sealing cover 2 is tightly fitted to the upper end surface of the annular portion 4, playing the role of automatically closing the liquid outlet pipe 1; through the lifting mechanism, the sampling bottle 7 and the pushing plate 8, the liquid outlet pipe 1 is automatically controlled to open and the sampling bottle 7 is driven to rise and fall; through the lifting mechanism, the dust cover and the annular portion 4, the sampling bottle 7 is lifted up and down. During the process, under the blocking effect of the annular portion 4, the top end of the dust cover is tightly attached between the top end surface of the sampling bottle 7 and the bottom end surface of the annular portion 4, thereby ensuring the airtightness between the sampling bottle 7 and the liquid outlet pipe 1; the automatic liquid pumping mechanism automatically extracts and collects the wine in the fermentation tank 45; by connecting the automatic liquid pumping mechanism to the upper end of one side and the lower end of the other side of the fermentation tank 45, it is only necessary to simultaneously activate the automatic liquid pumping mechanism, the lifting cylinder 43 and the conveying mechanism on both sides to achieve the function of automatically sampling the upper and lower layers of the wine in the fermentation tank 45;

[0025] The utility model has a high degree of automation and can automatically sample the upper and lower layers of the wine at the same time. It automatically controls the sealing of the sampling bottle 7 and the liquid outlet pipe 1, thereby preventing external air and dust from entering the fermentation tank 45 or the sampling bottle 7 during the sampling and collection process, and preventing the wine from flowing out of the sampling bottle 7, thereby reducing the contact of the wine with external air and dust during the sampling process. It has the advantages of high sampling efficiency, good sampling effect and low labor intensity.

[0026] Please refer to Figures 1 to 6 As shown, a wine fermentation tank sampling device includes a fermentation tank 45, and the upper end of one side and the lower end of the other side of the fermentation tank 45 are both connected to an automatic liquid pumping mechanism; the bottom of the outlet end of the automatic liquid pumping mechanism is connected to a liquid outlet pipe 1, and a sealing cover 2 is connected to the liquid outlet pipe 1 so as to slide up and down. A liquid outlet channel 3 for the circulation of wine is provided between the sealing cover 2 and the inner wall of the liquid outlet pipe 1, and an annular portion 4 for supporting the bottom of the sealing cover 2 is provided at the bottom of the liquid outlet pipe 1. Grooves are provided on both side walls of the bottom of the liquid outlet pipe 1, and compression springs 6 are connected between the top of the groove and both sides of the sealing cover 2. A conveying mechanism is provided below the liquid outlet pipe 1, and a sampling bottle 7 is placed on the conveying mechanism. A push plate 8 is provided in the middle above the sampling bottle 7 for passing through the inner side of the annular portion 4 and pushing the sealing cover 2. The outer side of the push plate 8 is fitted with a dust cover, and the lower end of the dust cover slides up and down on the outer side of the upper end of the sampling bottle 7. A convex ring portion 10 is provided on the side of the sampling bottle 7, and a supporting spring 11 is connected between the convex ring portion 10 and the bottom of the dust cover. A lifting mechanism is provided below the liquid outlet pipe 1 for driving the sampling bottle 7 to rise to the top of the dust cover and fit closely with the bottom of the annular portion 4.

[0027] As can be seen from the above description, when it is necessary to sample the wine in the fermentation tank 45, first, the external control system is used to control the conveying mechanism to start, and drive the empty sampling bottle 7 to the bottom of the liquid outlet pipe 1, so as to automatically convey the sampling bottle 7 to the bottom of the liquid outlet pipe 1; then the lifting mechanism is started to drive the sampling bottle 7 to rise in the direction close to the liquid outlet pipe 1. When the top surface of the dust cover is initially in contact with the bottom surface of the annular portion 4, the dust cover slides downward on the outer circumference of the upper end of the sampling bottle 7 under the blocking effect of the annular portion 4, and the push plate 8 passes through the inner hole of the annular portion 4 and continues to rise in the liquid outlet pipe 1. After the top surface of the push plate 8 contacts the sealing cover 2, it pushes the sealing cover 2 to leave the annular portion 4 and move upward. Until the sealing cover 2 rises to the preset position, the inner hole of the annular portion 4 opens, and the dust cover The top of the dust cover is tightly attached to the top surface of the sampling bottle 7 and the bottom surface of the annular portion 4, which plays a role in driving the sampling bottle 7 to automatically lift and lower for sampling and automatically control the opening and closing of the liquid outlet pipe 1; then, the automatic liquid pumping mechanism is started to pump the wine in the fermentation tank 45 into the liquid outlet pipe 1. Under the action of gravity, the wine flows from the liquid outlet channel 3 into the space between the sealing cover 2 and the annular portion 4, and then flows into the sampling bottle 7 through the inner hole of the annular portion 4, thereby automatically and efficiently collecting the wine; because the top of the dust cover is tightly attached to the top surface of the sampling bottle 7 and the bottom surface of the annular portion 4, the wine is prevented from flowing out of the sampling bottle 7. At the same time, it also prevents external air and dust from entering the fermentation tank 45 or the sampling bottle 7 during the sampling and collection process, thereby further improving the sampling effect and efficiency;

[0028] Afterwards, when the wine is collected, the lifting mechanism is started to reset, driving the sampling bottle 7 to descend. Under the elastic force of the supporting spring 11, the top of the dust cover is always tightly attached to the bottom end surface of the annular portion 4, preventing dust from entering the sampling bottle 7 and the fermentation tank 45 through the gap between the dust cover and the annular portion 4. Under the elastic force of the compression spring 6, the top of the push plate 8 is always in contact with the bottom end surface of the sealing cover 2 until the sealing plate is tightly attached to the annular portion 4 again. In order to avoid the sealing cover 2 from descending too fast and causing the liquid outlet pipe 1 to shake, the connection stability of the liquid outlet pipe 1 is ensured; when the sealing plate re-seals the inner hole of the annular portion 4, the push plate 8 continues to descend until it is re-fitted to the inner side of the top of the dust cover, and the push block and the dust cover When the movement stops, the lifting mechanism continues to drive the sampling bottle 7 to descend and reset to the conveying mechanism, which plays the role of automatically controlling the reset of the sampling bottle 7 and the sealing of the liquid outlet pipe 1 and the sampling bottle 7; by connecting the automatic liquid pumping mechanism to the upper end of one side and the lower end of the other side of the fermentation tank 45, when it is necessary to sample and test the upper and lower layers of wine in the fermentation tank 45, it is only necessary to simultaneously start the automatic liquid pumping mechanism, the lifting cylinder 43 and the conveying mechanism on both sides, which has a high degree of automation, can automatically sample the upper and lower layers of wine at the same time, and automatically control the sealing of the sampling bottle 7 and the liquid outlet pipe 1, which reduces the contact of the wine with external air dust during the sampling process, and has the advantages of high sampling efficiency, good sampling effect and low labor intensity.

[0029] Furthermore, the automatic liquid pumping mechanism includes a suction pipe 12, a piston 13, a pull rod 14 and an electric push rod 15 provided outside the fermentation tank 45. The suction pipe 12 is fixedly connected to the side of the fermentation tank 45; one end of the suction pipe 12 is located inside the fermentation tank 45, and a liquid inlet 16 is provided at the bottom, and a one-way valve 17 is provided in the liquid inlet 16; the other end of the suction pipe 12 is located outside the fermentation tank 45, and a liquid outlet 18 is provided at the bottom, and the liquid outlet pipe 1 is installed at the bottom of the liquid outlet 18, the piston 13 is slidably connected to the suction pipe 12 along the length of the suction pipe 12, and one end of the pull rod 14 is fixedly connected to one side of the piston 13; the other end of the pull rod 14 passes through the other end of the suction pipe 12 and is fixedly connected to the top rod of the electric push rod 15.

[0030] As can be seen from the above description, when it is necessary to sample the wine in the fermentation tank 45, first, the electric push rod 15 is started, and the top rod of the electric push rod 15 extends, driving the pull rod 14 to move the piston 13 from one end of the suction tube 12 toward the other end of the suction tube 12. As the piston 13 moves, the changing air pressure drives the wine in the fermentation tank 45 into the suction tube 12 through the liquid inlet 16. The wine moves with the movement of the piston 13 until it is discharged into the sampling bottle 7 through the opened liquid outlet tube 1, thereby automatically sucking the wine in the fermentation tank 45.

[0031] Furthermore, a sleeve 19 is threadedly connected to the outer peripheral surface of the bottom of the liquid inlet 16 , and a filter screen 20 is detachably connected to the bottom of the sleeve 19 . The filter screen 20 is located below the liquid inlet 16 .

[0032] From the above description, it can be seen that by setting up the filter screen 20, the raw materials in the fermentation tank 45 are prevented from being sucked into the sampling bottle 7 through the liquid inlet 16, thereby ensuring the sampling effect. The filter screen 20 is threadedly connected to the liquid inlet 16 through the sleeve 19, so that the filter screen 20 can be removed and replaced.

[0033] Furthermore, the bottom end surface of the sealing cover 2 is connected to a first sealing ring 21 in contact with the top end surface of the annular portion 4 , and the bottom end surface of the annular portion 4 is connected to a second sealing ring 22 in contact with the top end surface of the dust cover.

[0034] As can be seen from the above description, by providing the first sealing ring 21, when sampling is not required, external gas and dust are prevented from entering the fermentation tank 45 through the liquid outlet pipe 1, thereby improving the airtightness between the liquid outlet pipe 1 and the sealing cover 2; by providing the second sealing ring 22, when sampling, external gas and dust are prevented from entering the fermentation tank 45 or the sampling bottle 7 through the gap between the annular portion 4 and the top surface of the dust cover, thereby improving the sampling effect.

[0035] Furthermore, the groove includes a slide groove 23 and a guide groove 24. The top of the slide groove 23 is connected to the bottom of the guide groove 24. Sliding parts 25 are extended on both sides of the sealing cover 2. The sliding part 25 slides up and down along the length direction of the liquid outlet pipe 1 and is connected to the slide groove 23. The top of the sliding part 25 is connected to a guide column 26. The guide column 26 slides up and down along the length direction of the liquid outlet pipe 1 and is connected to the guide groove 24. The top of the guide column 26 and the top of the guide groove 24 are respectively fixedly connected to the two ends of the compression spring 6. The top side of the guide column 26 is connected to a limiting ring 27. The bottom of the guide groove 24 is provided with a blocking part 28 that prevents the limiting ring 27 from sliding out of the guide groove 24. The blocking part 28 is arranged in a ring shape, and the inner side of the blocking part 28 is provided with a third sealing ring 29.

[0036] As can be seen from the above description, when the sealing cover 2 descends or is pushed upward by the push plate 8, the guide column 26 moves downward or upward in the guide groove 24, and the sliding part 25 moves downward or upward in the slide groove 23, thereby ensuring that the sealing cover 2 moves downward or upward in the length direction of the liquid outlet pipe 1, avoiding the sealing cover 2 from affecting the sealing effect on the inner hole of the annular part 4 due to the lifting and shaking, thereby ensuring the lifting stability of the sealing cover 2 and further ensuring the airtightness of the liquid outlet pipe 1; through the third sealing ring 29, wine is prevented from entering the guide groove 24 and affecting the service life of the compression spring 6, thereby protecting the compression spring 6; through the limit ring 27 and the blocking part 28, the top of the guide column 26 and the compression spring 6 are prevented from moving out of the guide groove 24, thereby further ensuring the lifting stability of the sealing cover 2 and protecting the compression spring 6.

[0037] Furthermore, the dust cover includes a cover plate 9 and a cover ring 5. The bottom of the cover plate 9 is fixedly connected to the top of the cover ring 5. A circular hole 30 is provided in the middle of the cover plate 9 for placing the push plate 8. The hole wall of the circular hole 30 is connected to a fourth sealing ring 31 that contacts the outer circumferential side of the push plate 8. The bottom of the cover plate 9 is connected to a group of guide rods 32 arranged in an inverted T shape. The convex ring portion 10 is provided with a guide hole 33 for the vertical end of the guide rod 32 to pass through. The horizontal end of the guide rod 32 is against the bottom end surface of the convex ring portion 10. The support spring 11 is sleeved on the outer circumferential surface of the vertical end of the guide rod 32. The top side surface of the sampling bottle 7 is radially extended outward to provide a retaining ring portion 34 to prevent the cover plate 9 from moving above the push plate 8. The inner side of the upper end of the cover ring 5 is provided with a makeshift groove 35 for the retaining ring to slide up and down.

[0038] As can be seen from the above description, in the process of the lifting cylinder 43 driving the sampling bottle 7 to rise, when the top surface of the dust cover is initially in contact with the bottom surface of the annular portion 4, the cover plate 9 is driven to descend under the obstruction of the annular portion 4, and the vertical end of the guide rod 32 is directed downward in the guide hole 33. The cover ring 5 moves downward in a directional manner on the outer peripheral surface of the upper end of the sampling bottle 7 until the cover plate 9 is tightly fitted between the top surface of the sampling bottle 7 and the bottom surface of the annular portion 4, further ensuring the airtightness of the sampled liquid, and playing a role in improving the stability of the descent of the dust cover plate 2 and ensuring the sampling effect. In the process of the lifting cylinder 43 driving the sampling bottle 7 to descend, although the sampling bottle 7 is lowered as a whole, it is driven to rise under the elastic force of the supporting spring 11, and the guide rod 3 2 is directed upward in the guide hole 33, and the cover ring 5 is directed upward on the outer circumference of the upper end of the sampling bottle 7 to reset until the top surface of the cover plate 9 is flush with the top surface of the push plate 8 again; through the fourth sealing ring 31, after the sampling bottle 7 is sampled or before sampling is completed, dust is prevented from entering the sampling bottle 7 through the gap between the outer side surface of the push plate 8 and the inner wall of the circular hole 30 of the cover plate 9, which requires resampling or cleaning of the sampling bottle 7, thereby further ensuring the sampling effect and sampling efficiency; through the retaining ring portion 34 and the yielding groove 35, the dust cover is prevented from moving to the top of the push plate 8 under the elastic force of the support spring 11, thereby increasing the gap between the dust cover and the push plate 8, thereby further ensuring the sampling effect and sampling efficiency.

[0039] Furthermore, a support column 36 is connected to the bottom of the push plate 8, and a bottom of the support column 36 is connected to a base plate 37. The base plate 37 is detachably connected to the bottom end surface of the sampling bottle 7. The diameter of the support column 36 is smaller than the diameter of the push plate 8. A liquid storage cavity for storing wine is formed between the outer side surface of the support column 36, the inner wall of the sampling bottle 7 and the upper end surface of the base plate 37.

[0040] As can be seen from the above description, when the push plate 8 needs to be disassembled, it is only necessary to disassemble the chassis 37, manually grab the push plate 8 and take out the support column 36 and the chassis 37.

[0041] Furthermore, the conveying mechanism includes a turntable 39 and a motor 40, and the driving end of the motor 40 is fixedly connected to the bottom end of the turntable 39; the turntable 39 is evenly provided with limiting grooves 41 along its circumference for placing the sampling bottles 7, and the bottom of the limiting grooves 41 is provided with a through hole 42 for the driving end of the lifting mechanism to pass through.

[0042] As can be seen from the above description, when sampling is required, the motor 40 is started, and the motor 40 drives the turntable 39 to move the empty sampling bottle 7 to the bottom of the liquid outlet pipe 1, thereby automatically transporting the sampling bottle 7 to the bottom of the liquid outlet pipe 1; through the limit groove 41, the sampling bottle 7 is prevented from shaking during the process of transportation and lifting with the rotation of the turntable 39, thereby ensuring the movement of the sampling bottle 7 and the stability of sampling.

[0043] Furthermore, the lifting mechanism includes a lifting cylinder 43 and a push block 44 . The lifting cylinder 43 is located below the turntable 39 . The top rod of the lifting cylinder 43 is detachably connected to the push block 44 . The diameter of the push block 44 is smaller than the diameter of the through hole 42 .

[0044] When the empty sampling bottle 7 is to be taken to the lower part of the liquid outlet pipe 1, the lifting cylinder 43 is started, the top rod of the lifting cylinder 43 is extended, and the push block 44 is driven to rise through the through hole 42 toward the direction close to the liquid outlet pipe 1. After the push block 44 contacts the bottom of the sampling bottle 7, the top rod of the lifting cylinder 43 continues to extend, thereby driving the sampling bottle 7 to rise toward the direction close to the liquid outlet pipe 1 through the push block 44. When the top surface of the dust cover is initially in contact with the bottom end surface of the annular portion 4, the dust cover slides downward on the outer circumference of the upper end of the sampling bottle 7 under the obstruction of the annular portion 4, and the pushing plate 8 continues to rise through the inner hole of the annular portion 4, pushing the sealing cover 2 to move upward together until the sealing cover 2 rises to the preset position, and the top end of the dust cover is attached between the top surface of the sampling bottle 7 and the bottom end surface of the annular portion 4. After the liquid is taken, the function of driving the sampling bottle 7 to automatically lift and sample and automatically control the opening and closing of the liquid outlet pipe 1 can be realized.
